CONTROL DEVICE FOR WABPING-MACI-IINES.

Specification of iette'rs Patent.

Patented Jan. 16, 1917.

Original application filed March 21, 1914, Serial No. 826,142. Divided and this application filed April 30,

To all whom it may concern:

Be it known that I, EDWARD BLOOM, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Control Devices for'Warping-Machines, of'which th following is a specification.

This application is a division of my application for patent for improvements in warping machines, filed March 21st, 1914, Serial No. 826142.

This invention relatesv to warping machines, and it has for its principal object to provide a warping machine with a simple and reliable means for stopping the rotation of the reel when a predetermined length of warp has been wound on the reel.

According to this invention the reel-driving mechanism includes. a disconnective clutch-connection whose movable clutch member is controlled by a shiftable powertransmitting means which is moved from the reel in the direction to shift said member for breaking the clutch-connection and which is provided with a normally activedetent wihch, on said movement of said means, locks the latter against return, leavingthe power out off until the'operator restablishes it; preferably the mechanism for actuating said means is a'pattern mechanism having a disconnective connection with the reel (whereby it is driven) so that on disestablishing said connection the pattern mechanism may be moved to allow reestablishing the aforesaid clutch-connection on releasing the detent, and also to reset the pattern mechanism all without disturbing the reel.

In the accompanying drawing, Figure l is a front elevation of so much of the machine as directly includes said improvements; and, Fig. 2 is a plan view of the improvements.

The frame a, reel shaft 0 journaled in the frame in the usual manner, the reeldriving band or hoop (Z, the rotary. shaft 6 carrying a friction wheel f to engage the band cl and so drive the reel, the lever g in which said shaft is journaled and the lever it operated from suitable means, such as a treadle (not shown), so as to effect movement of lever 9 up and down to shift the friction wheel f into and out of contact with the band (Z, are or, may be all substantially the same as in any warping machine of the Serial No. 24,883.

type of that herein shown, to wit, ahorizontal warping machine. In the present in.- stance, the pulley z rotated by suitable means (not shown) is freely revoluble on the shaft e and forms one member of a clutch, of which the other member is the part marked in; Fig. 1, being splined on said shaft. On shifting this member tot-he left in Fig. 1 the power istransmitted from i to 6; when shifted to the right, i rotates idly.

In a bracket Z projecting from the frame is fulcrumed a lever having a fork. a engaged in the peripherallygrooved collar 0 of the clutch member is and being normally influenced by a spring 39 to maintain clutch member is engaged with the other clutch memberpulley 2'. Pivoted to one arm of this lever, which overhangs a part ofthe frame a, is a pendent detent m. p I

In brackets q secured to the frame above the pulley shaft 6 is arranged the shaft r affording a fulcrum for four levers, one of which, 8, is connected with the lever m by the rod t. In these brackets is journaled a shaft it having a handle c at oneend whereby it may be manually rotated and carrying a sprocket wheel 11 over whichextends an endless pattern chain :0, provided with (in the present instance) four balls 3 The lever 8 rests on this pattern chain in vertical al nement with one of these balls, so that, as the chaln is advanced once 1n each circuit thereof the lever is elevated.

' I The shaft a carries a fixed clutch member a and on it is splined a movable clutch member 2 having a worm-wheel 3 meshing with the worm 4 on the shaft 0 of the reel. For moving the clutchmember Z I provide the sliding fork 5 arranged on the shaft 1' and engagedin thegroove 6 of said clutch. member, said fork being normally forced to the right in'Fig. 1 by a spring 7 coiled between the fork and the left-hand bracket 2 and thereby maintaining the disconnective connection z-2 normally established. 8 is a set screw for securing the fork in a position where said connection z2 is disestablished.

Operation: In the winding of each section or other length of warp on the reel the alarm device is actuated three times (in the present instance), first to notify the attendant when to insert the first lease cord, next to notify when to insert the second lease cord and finally to signal the approach of the point in the section where it should be cut off thereupon the reel is automatically brought to a standstill. These operations are performed by the levers 9 and s in the order of their arrangement, from right to left in Fig. 1, as they are successively lifted by the balls on the pattern chain. The reel, upon being brought to a stop by the elevation of lever s, is maintained at astandstill by the detent m which, on the movement of lever m to shift clutch member I? out of clutching engagement with pulley 2', seats upon the frame and thus prevents return movement of said lever and the clutch member. Having cut off and tied the section thus wound on the reel and attached the end of the new section to the reel, the attendant employs fork 5 to disestablish the connection 2-2, whereupon handle 4) is turned to shift the pattern chain forwardly just enough to clear the ball which stopped the machine from beneath the lever s. Detent m is then moved out of engagement with the frame, allowing the lever m and consequently the clutchmember I: to return to their normal positions, whereby the reel is again put in motion.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A warping machine including, in combination, a frame, a reel journaled therein, means to rotate the reel including clutch members forming a clutch connection and one being withdrawable out of clutching engagement with the other, and means, including a repeating mechanism, for transmitting withdrawing motion from the reel to the first-named clutch member.

2. A warping machine including, in combination, a frame, a reel journaled therein,

means to rotate the reel including clutch members forming a clutch connection and one being withdrawable out of clutching engagement with the other, and means including a disconnective clutch connection for transmitting withdrawing motion from the reel to said first-named member.

3. A warping machine including, in com bination, a frame, a reel journaled therein, means to rotate the reel including clutch members forming a clutch connection and one being withdrawable out of engagement with the other, and means, including a dis connective clutch connection and a repeating mechanism, for transmitting withdrawing motion from the reel to said first-named member.

4. A warping machine including, in combination, a frame, a reel shaft journaled therein, a reel carried by said shaft, a repeating mechanism operatively connected with and driven by the reel shaft, a lever engaged with the repeating mechanism, means to rotate the reel including clutch members forming a clutch connection and one being Withdrawable out of clutching engagement with the other, another lever fulcrumed in the frame and engaged with the first-named clutch member, and a link connecting said levers.

5. A warping machine including, in combination, a frame, a reel journaled therein, means to rotate the reel including clutch members forming a clutch connection and one being withdrawable out of clutching engagement with the other, means for transmitting withdrawing motion from the reel to the first-named member, including a repeating mechanism, disconnective powertransmitting mechanism connecting the repeating mechanism and reel, back and forth moving means actuated by the pattern-mechanism and operatively connected with the first-named clutch member, and a detent normally active tolock the last-named means against return upon movement in one direction.

In testimony whereof I afliX my signature.

EDWARD BLOOM.
